Glass Concepts

Every Loewen window and door mirrors a fascinating journey.
It began at the turn of the twentieth century on the lonely prairies of southern Manitoba.
Here in the village of Steinbach, a group of Mennonite families, including the Loewens, had migrated from Russia.
Among the first things made by the Loewen millwork for the fast-growing community were humble items like church pews and bee-keeping equipment.
But soon, windows and doors became our specialties.
The key to our success is simple: while we've remained faithful to our roots - particularly in our deeply held traditional craft values and our work ethic - we've also grown to embrace new technologies and ideas from places as diverse as Europe, Japan, America and, of course, Canada.

Established in 1986, Optimum Window has made its mark in the steel windows industry as the largest and most diversified manufacturer of Fire Rated windows in the United States.
